Description

   Beauty contact lenses   

The present invention relates to a contact lens for beauty, and more particularly, to a patterned area composed of colored parts of a novel aspect, capable of adapting to the eyes of the wearer and suppressing the appearance of inconsistency while making the pupil look It is large and can provide a beauty contact lens which has a natural makeup (beauty) effect that was not previously available.

Conventionally, as one of the contact lenses worn on the surface of the eyes, a number of cosmetic contact lenses have been proposed to provide a cosmetic effect by colored portions. Conventional contact lenses for beauty include those that change the color of the pupil, and those that make the pupil appear larger.

The former is only coloring the inner peripheral side of the boundary between the black eyeball and the white eye (limbal), and using the colored part to cover the part of the black eyeball (around the pupil) where the color of the iris can be seen through the cornea. This makes the part of the black eyes look different from the original color. On the other hand, as shown in Japanese Patent Application Publication No. 2008-511025 (Patent Document 1), the latter is a colored region having a ring shape that is larger than the outer diameter of the corneal limbus and even covers the white portion of the eyes to the periphery of the pupil. And make the black eyes look bigger.

Regarding the latter, the beauty contact lenses that make the black eyes look larger not only make the outer diameter of the black eyes larger, but also clearly emphasize the outer edges of the black eyes to make them clear, thereby enabling the eyes and even the entire face to be made clear. His expression looked cute or bright. Therefore, the outer edge of the colored region is formed as a circular line which can be clearly recognized.

However, the present inventors conducted research repeatedly, and found that if the outer edge of the colored area is formed with a clear circular line, and the boundary line between the black eyeball and the white eye is set as a clear and distinct line, it is obvious to others. Eyes (prosthetic eyes) that leave too artificial impressions and are easily seen as robots, especially for ordinary people who are not models or the like, may not be able to achieve the purpose of "making the eyes look beautiful overall".

Furthermore, based on this knowledge, the present applicant disclosed a novel colored contact lens in Japanese Patent Application Laid-Open No. 2013-65059 (Patent Document 2) and Japanese Patent Application Laid-Open No. 2013-130658 (Patent Document 3). By adjusting the concentration or light transmittance on the outer peripheral side of the colored area covering the outer edge of the black eyeball, the unnatural appearance is avoided, thereby reducing the artificial impression.

The present invention was completed with the above-mentioned circumstances as a background, and the problem to be solved is to provide a novel cosmetic contact lens with a structure different from that of Patent Literature 2 and Patent Literature 3, which can avoid colored contact lenses as described in Patent Literature 1. The unnatural appearance of the glasses, while adapting to the wearer's eyes and suppressing the appearance of dissonance, makes the pupils look larger.

The present invention is characterized by a cosmetic contact lens in which a peripheral portion located on the outer peripheral side of the optical portion is composed of a colored portion with a tapered shape that decreases in width from the outer peripheral side of the lens toward the inner peripheral side. A plurality of cone-shaped spokes are arranged in the circumferential direction of the lens, whereby a ring-shaped beauty pattern area is set as a whole, and the outer diameter size of the beauty pattern area is set to 11.0 to 14.0 mm. The beauty The patterned area is applied to the inner peripheral side and the outer peripheral side of the outer edge of the cornea of the wearing eye. The inner peripheral end of the cosmetic patterned area is located on the cornea, and the outer peripheral end is located on the sclera. Adjacent the conical spokes are separated from each other, and non-colored portions extending across the entire length in the radial direction are provided between them. The separation distance between the conical spokes adjacent to each other in the circumferential direction of the lens is set to the minimum outer peripheral end. The non-colored portion is set to 0.01 to 0.20 mm, and the width dimension is increased from the outer peripheral side of the lens toward the inner peripheral side.

The present invention relates to a person who utilizes a color assimilation phenomenon that is an illusion of the eye in a cosmetic pattern area that covers the inner peripheral side and the outer peripheral side of the corneal outer edge portion, and particularly changes the radial direction by assimilating the assimilation phenomenon. As a basic technical idea, while adapting the beauty pattern area to both the cornea's black eyeballs and the sclera's eyes white, and suppressing the appearance of inconsistency, while making the pupil look larger.

That is, in a cosmetic contact lens having the structure according to the present invention, a gap-shaped non-colored portion is provided between the tapered spokes constituting the patterned area for beauty, extending continuously throughout the radial direction. As a result of this gap, astigmatism occurs between the tapered spokes and the eyes that are seen through the non-colored portion, as the colors are close to each other. As a result, in the cosmetic pattern area, an appearance suitable for the eyes of the wearer is exhibited.

Moreover, the inner peripheral part of the cosmetic pattern area located on the black eyeball part of the cornea is adapted to the wearer's black eyeball part to present a natural appearance, and the outer peripheral part of the cosmetic pattern area on the white part of the sclera eye is adapted to the wearer The white part of the eyes can make the outer edge of the cornea bigger in a natural way.

In addition, the non-colored portion in the beauty pattern area is made larger in width from the outer periphery toward the inner periphery, so that the assimilation phenomenon gradually changes in the radial direction, and in the inner and outer periphery portions, the assimilation phenomenon gradually changes. Variety. That is, the inner peripheral portion of the beauty pattern area advantageously exerts the assimilation effect of the color of the tapered spokes close to the color of the cornea of the wearer. The color of the cornea is gradually approaching the assimilation of the color of the tapered spokes. In this way, the assimilation phenomenon is transformed in the radial direction. For example, even if the color of the tapered spokes is different from the color of the cornea of the wearer, it looks integrated with the color of the natural cornea as a whole and presents a less inharmonious appearance. Therefore, for example, it is possible to give a clearer color than the wearer ’s cornea while making the outer edge of the cornea look larger, while suppressing the sense of inconsistency caused by the difference from the original corneal color of the wearer, thereby giving the overall A more natural look.

In the present invention, one or a plurality of the following aspects can be appropriately combined and applied.

One aspect that can be applied to the present invention is a cosmetic contact lens in which the width of the spokes whose width is set to the maximum outside the width of the tapered spokes is set to 0.1 to 1.0 mm.

According to this aspect, the assimilation phenomenon in the outer peripheral portion of the beauty pattern area is improved, and a more natural appearance can be expressed. If the width of the spokes at the outer peripheral end becomes less than 0.1 mm, there is a case where the sharpness in appearance decreases and it is difficult to obtain a cosmetic effect in which the outer edge of the cornea of the wearer becomes noticeably larger using a cosmetic pattern. On the other hand, if the width of the spokes at the outer peripheral end exceeds 1.0 mm, there may be cases where the sharpness in appearance becomes conspicuous, and the outer edge of the cornea of the wearer may have a sense of inconsistency in appearance due to the cosmetic pattern imparted. .

One aspect that can be applied to the present invention is a cosmetic contact lens in which, in the aforementioned tapered spokes adjacent to each other in the circumferential direction of the lens, the separation distance Da at the inner peripheral end, the separation distance Db at the outer peripheral end, and the middle The partial separation distance Dc has a relationship of 0 <Db <Dc <Da.

According to this aspect, as illustrated in FIG. 7 or FIG. 11, the width dimension of the non-colored portion provided between adjacent tapered spokes is set at any position of the middle portion between the inner peripheral end and the outer peripheral end. It is larger than the outer peripheral end and smaller than the inner peripheral end. As a result, especially in the inner and outer peripheral portions, the gradual increase in the assimilation phenomenon can promote the assimilation to the cornea in the inner peripheral portion and the assimilation from the cornea to the sclera in the peripheral portion.

One aspect that can be applied to the present invention is a cosmetic contact lens, that is, the separation distance Da and the separation distance Db between the inner peripheral end and the outer peripheral end of the tapered spokes adjacent to each other in the circumferential direction of the lens, The width dimension of the inner peripheral end of the tapered spoke is set to a value smaller than Da, and the width dimension of the outer peripheral end is set to a value larger than the Db.

According to this aspect, in the beauty pattern area, the assimilation phenomenon to the cornea in the inner peripheral portion and the assimilation phenomenon to the sclera in the outer peripheral portion are respectively increased, and it is possible to further reduce the appearance of the uncoordinated feeling.

One aspect that can be applied to the present invention is a cosmetic contact lens in which the tapered spokes are formed by a bottom edge located on the outer peripheral end and extending from both ends of the bottom edge toward the inner peripheral side, respectively. A triangular shape composed of two hypotenuses and each hypotenuse is longer than the bottom.

According to this aspect, it is possible to express the assimilation phenomenon and its radial gradation effect by the relatively simple shape of the tapered spokes.

One aspect that can be applied to the present invention is a cosmetic contact lens in which the tapered spokes are provided as colored portions having substantially fixed brightness and hue, chroma, and density throughout the entire body.

According to this aspect, although the cone-shaped spokes are formed in a generally fixed color as a whole, the assimilation phenomenon as described above and the radial gradient effect can adapt the cornea on the inner peripheral side while facing the outer periphery with a natural appearance. A cosmetic effect that makes the outer edge of the cornea look larger.

One aspect that can be applied to the present invention is a cosmetic contact lens in which the tapered spokes are provided with substantially the same colored portions throughout the entire body.

According to this aspect, although the tapered spokes are formed to be fully colored, in the wearing state, a natural appearance can be expressed by assimilating the corneal color of the wearer through the non-colored area and the third person.

One aspect that can be applied to the present invention is a cosmetic contact lens in which the plurality of tapered spokes are arranged concentrically with respect to the geometric center of the optical portion or the lens.

According to this aspect, in a normal contact lens for correcting nearsightedness, farsightedness, and presbyopia, it is possible to skillfully arrange the patterned area for beauty so as to overlap the outer peripheral portion of the cornea of the wearer.

One aspect that can be applied to the present invention is a cosmetic contact lens in which the aforementioned conical spokes having the same shape and size are arranged at equal intervals in the circumferential direction.

In this aspect, regarding the appearance pattern of the beauty pattern area, it is easy to prevent the appearance of the particular part of the circumference from appearing on the appearance, so that it has a substantially uniform appearance in the circumferential direction. Furthermore, in this aspect, it is also possible to set all the conical spokes constituting the pattern area for beauty to conical spokes having the same shape and size. In this case, adjacent conical spokes may be fixed through The shape and size of the non-colored portions are arranged in the circumferential direction. Of course, in this aspect, it is also possible to arrange conical spokes having different shapes or sizes between the circumferential directions of a plurality of conical spokes having the same shape and size arranged at equal intervals in the circumferential direction.

One aspect that can be applied to the present invention is a cosmetic contact lens in which the width in the circumferential direction of the lens in the non-colored portion is continuously oriented from the outer peripheral side of the lens over the entire length in the radial direction of the non-colored portion. The manner in which the inner peripheral side of the lens becomes larger gradually changes.

According to this aspect, the assimilation phenomenon is exerted in the radial direction in a smoother transition state throughout the entire length of the non-colored portion, thereby enabling a more natural presentation manner.

One aspect that can be applied to the present invention is a cosmetic contact lens in which the value of the length dimension in the radial direction of the lens in the non-colored portion is set to 0.5 to 4.5 mm and is set to the maximum The value of the difference Da-Db between the width dimension Da of the peripheral end and the width dimension Db of the outer periphery set to the minimum is set to 0.02 to 3.0 mm.

According to this aspect, the radial length of the assimilation phenomenon can be ensured in a manner that the gradation effect of the assimilation phenomenon is more effectively exerted in the beauty pattern area.

According to the present invention, it is possible to provide a new gradation in the radial direction by utilizing the assimilation phenomenon with respect to the color of the eyes of the wearer in a cosmetic pattern area composed of a specific colored portion and a non-colored portion. Beauty contact lenses.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, the "color assimilation phenomenon" used in the present invention will be described. The well-known "color assimilation phenomenon" is a phenomenon in which a color looks similar to another color when it is surrounded or sandwiched by another color, which is a kind of optical illusion. Specifically, the assimilation phenomenon of colors will be described using the reference diagram shown in FIG. 1.

That is, in FIG. 1 (a), a plurality of parallel gray lines arranged at a fixed interval are illustrated as a certain color, and in (a1), the gap between adjacent gray lines is set as another A white line of one color, on the other hand, in (a2), a gap between adjacent gray lines is set as a black line of another color. When (a1) and (a2) are observed in contrast, the assimilation phenomenon of gray lines which are the same color, and (a2) appears to be thicker than (a1).

In FIG. 1 (b), a plurality of parallel black lines arranged at a fixed interval are illustrated as a certain color. In (b1), the gap between adjacent black lines is set as another color. A white line of one color, on the other hand, in (b2), a gap between adjacent black lines is set as a gray line of another color. If (b1) and (b2) are observed in contrast, the assimilation phenomenon of black lines which are the same color, and (b2) appears to be closer to gray and black than (b1).

Moreover, in FIG.1 (c), similar to (a), the multiple parallel black line is arrange | positioned adjacent to and parallel to each other via a gray line, but the distance between them is larger than (a). If you observe (a) and (c) in contrast, you can see that if the interval between the lines is too large, the color assimilation phenomenon is difficult to occur, but the contrast phenomenon with a clear and clear boundary with the surrounding colors will occur.

The cosmetic contact lens of the present invention is a person who uses such an assimilation phenomenon, but is not limited thereto. In the present invention, in addition to the assimilation phenomenon of color, the assimilation phenomenon is gradually changed in the radial direction of the pupil. That is, the assimilation effect and its degree in the assimilation phenomenon of colors are different according to the size of the adjacent gaps of a certain color, as can be seen from (a), (b), and (c) of FIG. 1. The present inventors have found that by focusing on this phenomenon, the direction or degree of assimilation of color can be gradually changed and controlled in the radial direction of the pupil. Furthermore, by placing the colored portion of a specific shape on the contact lens in a specific arrangement, and constituting a cosmetic pattern area composed of the colored portion and the non-colored portion, the following novel cosmetic contact lens can be realized, that is, The outer peripheral part can be adjusted to the appearance of the sclera and to a certain degree of clarity, while making the pupil (the part of the black eyeball) look larger in appearance, while making it look natural to the human eye The pupil color is adapted to reduce the appearance of dissonance.

FIG. 2 is a front view of a cosmetic contact lens 10 as a first embodiment of the present invention. The cosmetic contact lens 10 has the shape of a conventional contact lens known in the art, and is formed in a partial spherical shell shape having a front surface with a convex shape that is set as a spherical crown shape and a rear surface with a concave shape that is set as a spherical crown shape. To wear on the surface of the cornea that overlaps the eye.

In addition, the material of the cosmetic contact lens 10 is not limited. For example, in addition to a rigid lens such as an RGP lens (oxygen-permeable lens) or PMMA (polymethyl methacrylate), a material such as PHEMA (polymethyl methacrylate) can also be used. Ethyl) and other non-aqueous materials such as acrylic elastomers, and highly oxygen-permeable soft contact lenses such as silicone hydrogels. In particular, soft contact lenses generally cover the white part of the eyes with a large diameter compared with rigid contact lenses, and the amount of movement on the cornea is small when worn, so they can be preferably used in the present invention.

In addition, the cosmetic contact lens 10 includes an optical portion 14 that passes through a substantially circular central area around a center point that is substantially the same as or slightly offset from the geometric center 12 of the lens. The optical portion 14 has a larger outer diameter φA than the pupil of the human eye, and is superimposed on the cornea when placed on the pupil.

Further, a peripheral portion 16 is provided on the outer periphery of the optical portion 14 so as to surround the optical portion 14 with a predetermined width and a ring shape. The peripheral portion 16 deviates from the projection optical path to the eye optical system in the wearing state, and is provided in consideration of the stability of the position on the eyeball, the improvement of the wearing feeling, and the like. Further, an outer peripheral end of the peripheral portion 16 is provided as an edge portion 18 connecting the front surface of the lens and the rear surface of the lens.

In addition, the optical unit 14 can have specific optical characteristics and can provide correction functions for vision abnormalities such as nearsightedness, farsightedness, and presbyopia. As a result, the cosmetic contact lenses (lenses) 10 can also serve as vision correction contact lenses. . However, the cosmetic contact lens 10 of this embodiment may be a non-vision correction contact lens which does not have optical characteristics for vision correction. When it is provided as a contact lens for non-vision correction, it can be used, for example, as a cosmetic lens (contact lens for cosmetic or cosmetic purposes).

In addition, the outer diameter dimension (DIA) of the cosmetic contact lens 10 of this embodiment is such that it can cover the part of the black eyeball 20 (cornea) of the eye as a whole, and cover the part of the eye white 22 (sclera) with a predetermined width. set up. That is, the DIA of the cosmetic contact lens 10 is larger than the outer diameter dimension φ B of the boundary line (corneal limbus) 24 of the black eyeball 20 and the white eye 22 of the eye. The edge portion 18 of the edge is closer to the inner peripheral side. Furthermore, the black eyeball 20 is an area where the color of the iris of the eye can be seen from the outside, and an area where the iris can be seen through the transparent cornea. Therefore, the boundary line 24 can be understood as the cornea and the white sclera on its outer peripheral side. Junction line.

Furthermore, the cosmetic contact lens 10 is provided with a beauty pattern area 26 composed of a colored ribbon portion that expands in a substantially annular shape as a whole.

In particular, in the present embodiment, the beauty pattern area 26 is disposed concentrically around the lens geometric center axis (for example, the lens optical axis) of the peripheral portion 16 passing through the geometric center 12. Further, in a state where the cosmetic contact lens 10 is worn on the eye, the cosmetic pattern area 26 has a diameter that expands in the radial direction across both the inner peripheral side and the outer peripheral side of the limbus (outer limbus portion) 24 of the eye. In the width direction, on the inner peripheral side of the limbus 24, the cosmetic pattern area 26 overlaps the black eyeball 20, and on the outer peripheral side of the limbus 24, the cosmetic pattern area 26 overlaps the eye white 22.

In addition, the beauty pattern area 26 is preferably set such that the inner diameter dimension φ C (see FIG. 2) does not substantially overlap the pupil in most situations of the wearer's daily life. This suppresses the influence of the beauty pattern area 26 on vision. On the other hand, the outer diameter dimension of the beauty pattern area 26 is set so that the eye white 22 can be covered with a predetermined width. Thereby, the cosmetic effect of making the limbus 24 look larger in appearance is exerted.

The beauty pattern region 26 may be provided up to the outermost peripheral edge portion 18 of the beauty contact lens 10, but in this embodiment, the outer diameter dimension φ D (see FIG. 2) of the beauty pattern region 26 is set to It is smaller than the outer diameter dimension (DIA) of the cosmetic contact lens 10, and a non-colored outer periphery having a ring shape extending in a circumferential direction with a predetermined width in the radial direction is provided between the cosmetic pattern area 26 and the edge portion 18 Area 30. The presence of the outer transparent region 30 can ensure the radial dimension of the peripheral portion 16 which contributes to lens position stability and the like while wearing, and adjust the outer diameter dimension of the beauty pattern region 26 with a large degree of freedom.

The beauty pattern area 26 in the present embodiment is configured as a tapered spoke formed by a colored portion having a tapered shape from the outer peripheral side of the lens toward the inner peripheral side, and the width dimension of the circumferential direction is reduced. A plurality of 28 are arranged in the circumferential direction of the lens, so that the middle portion inside and outside in the radial direction is expanded in the circumferential direction with a substantially fixed width dimension. That is, the beauty pattern area 26 has a colored portion of the tapered spokes 28 that is considered to be dark in appearance, and a non-colored portion 32 that is located between the adjacent tapered spokes 28 and 28 and has an appearance. Recognized as transparent (including colorless transparent and colored transparent). Thereby, the plurality of tapered spokes 28 are arranged concentrically with respect to the optical portion 14 or the geometric center 12 of the lens.

In addition, the inner diameter dimension of the beauty pattern region 26 is a diameter dimension of a circle connecting the innermost points of the plurality of tapered spokes 28, and the outer diameter dimension of the beauty pattern region 26 is a plurality of tapered spokes. The diameter of the circle connected to the outermost point of 28. When the beauty pattern area 26 is formed by a plurality of tapered spokes 28 having different radial lengths as in another aspect described below, the smallest inscribed circle and the largest outer inscribed circle of the plurality of tapered spokes 28 are used. Understand the inner diameter φ C and outer diameter φ D of the beauty pattern area 26 (refer to FIG. 7 for φ C). However, the inscribed circle or circumscribed circle in the beauty pattern area 26 need not be a true circle, and may be, for example, a vertically or horizontally long oval shape.

In order to sufficiently obtain a targeted makeup effect, the beauty pattern area 26 is generally preferably formed in a radial width dimension of 0.5 to 4.5 mm, and more preferably formed in a radial width dimension of 1.0 to 3.5 mm. . In addition, the radial width dimension of the beauty pattern area 26 is preferably set to be constant over the entire length in the circumferential direction. That is, although the inner peripheral edge and the outer peripheral edge of the beauty pattern area 26 can be constituted by, for example, the tapered spokes 28 as described above, the smallest inscribed circle (not limited to a true circle) and the largest inscribed circle (and It is not limited to a true circle), but by designing these inscribed circles and the circumscribed circles concentrically and making them similar shapes, the radial width dimension of the beauty pattern area 26 can be fixed throughout the entire circumference. On the other hand, for example, by shifting the centers of the inscribed circle and the circumscribed circle of the plurality of tapered spokes 28 from each other, or by setting the inscribed circle and the circumscribed circle to a non-similar shape, the beauty pattern area 26 can also be made. The radial width dimension changes in the circumferential direction.

The inner diameter dimension φ C of the beauty pattern area 26 is preferably set to φ 6 mm or more, and more preferably set to φ 7 mm or more. In addition, the size of the cornea of an ordinary person is taken into consideration so that the inner periphery of the cosmetic pattern area 26 partially covers the black eyeballs 20, and the inner diameter dimension φ C of the cosmetic pattern area 26 is preferably set to φ 13 mm or less.

On the other hand, in the area outside the beauty pattern area 26, the area where the eye white 22 is sufficiently left when worn is more natural, and the beauty of the eye white 22 is more effective for the makeup effect. The diameter φ D is preferably set to φ 14 mm or less. Furthermore, the outer diameter dimension φD of the beauty pattern area 26 is preferably set to φ11mm or more, and more preferably set to φ12mm or more, so that the eye white 22 can be covered with a predetermined width.

Here, the beauty pattern area 26 is constituted by a plurality of tapered spokes 28 arranged at specific intervals in the circumferential direction, not only giving a cosmetic effect that makes the limbus 24 look larger in appearance as described above, but also For the third person observing the wearer, suppress the appearance of the appearance after giving the wearer's eyes a natural fit by suppressing unnaturalness.

If specific illustration is made with reference to FIG. 3, the gray background equivalent to the cornea shown in FIG. 3 (a) is overlapped with a plurality of blacks constituting the beauty pattern area 26 in the contact lens 10 for beauty shown in FIG. 2 The tapered spokes 28 are shown in Fig. 3 (b). In addition, in the following drawings describing the beauty pattern area 26, the illustration of the lens outer shape is omitted. In addition, in order to facilitate the description and understanding of the invention, it is shown in an enlarged view.

As can be seen from FIG. 3 (b), in the black tapered spokes 28, a gray assimilation phenomenon that looks close to the ground color occurs. Further, it can be seen that the degree to which the black tapered spokes 28 look close to the gray of the ground color is different from the inner peripheral side and the outer peripheral side of the beauty pattern area 26. Compared to the outer peripheral side, the black tapered spokes 28 on the inner peripheral side look closer to the gray of the ground color.

This means that not only the color assimilation phenomenon occurs, but also that the degree of color assimilation changes in the radial direction of the beauty pattern area 26. Moreover, in the wearing state, in the inner peripheral portion of the cosmetic pattern area 26, the assimilation phenomenon of the colored portion, that is, the tapered spokes 28, is close to the color of the eyes that can be seen through the non-colored portion 32. On the other hand, in On the contrary, the outer peripheral portion of the cosmetic pattern area 26 strongly exhibits an assimilation phenomenon in which the color of the eyes is close to that of the tapered spokes 28. As a result, the transition effect from the inner peripheral side to the outer peripheral side of the cosmetic pattern area 26 is transferred from the color of the eye to the color of the colored portion without any appearance in the appearance.

Further, in the outermost portion of the beauty pattern area 26, each of the tapered spokes 28 extends from the black eyeball to the area of the white eye and is positioned. Since the non-colored portion 32 is also provided between the adjacent tapered spokes 28 and 28 in the outermost part of the beauty pattern area 26, the white eyes visible through the non-colored portion appear to be close to the cone. Assimilation of the color of the colored portions of the spokes 28. As a result, the boundary line between the colored portion and the white of the eyes in the outer peripheral portion of the cosmetic pattern area 26 becomes unclear in appearance.

In this way, the beauty pattern area 26 is adapted to the color of the wearer's black eyeballs on the inner peripheral portion, and the color of the tapered spokes 28 transitions toward the outer portion without discomfort, and further, the beauty pattern area 26 The outermost part is extended and extended to be more peripheral than the black eyeballs. This can exert the makeup effect that makes the wearer's black eyeballs look larger in appearance, while suppressing the boundary line between the eyeballs and the eyes. Naturally adapted appearance.

That is, in the wearing state of the beauty contact lens 10 of this embodiment, by using the assimilation phenomenon of the color gradually changing in the radial direction of the beauty pattern area 26, the color of the iris from the inner peripheral part to the cone of the outer peripheral part. The color of the shaped spokes 28 transitions smoothly, and then, at the outermost part, the color of the tapered spokes 28 and the color of the sclera (eye white) are assimilated, thereby reducing the appearance of dissonance. The adaptation of this color is such that, for example, the boundary between the cornea (black eyeball) and the sclera (white eye) cannot be clearly distinguished from the anatomy (exterior corneal limbus or limbal limbus). The boundary at which the color of the iris is gradually changed to the color of the tapered spokes 28 and then gradually to the color of the sclera by the assimilation of the colors is clearly identified. Moreover, by blurring and gradually transitioning the boundary between the color of the eyes and the color of the tapered spokes 28, the tapered spokes 28 that are artificially colored to make the black eyes appear larger appear closer to the wearer's eyes. The appearance of colors.

In order to obtain such an effect, the colored portions constituting the beauty pattern area 26 are set as tapered spokes 28 as shown in the example, and a space is provided between adjacent tapered spokes 28 and 28. The non-colored portion 32 extending continuously in the radial direction over its entire length.

If it is different from such a configuration according to the present invention, for example, instead of the tapered spokes 28, a rod-shaped (rectangular) spoke extending in a radial direction with a fixed width dimension is used, the difference between the adjacent spokes in the circumferential direction In contrast to the present invention, the width of the colored region is smaller on the inner peripheral side and larger on the outer peripheral side. Therefore, the assimilation effect in the outermost part extending to the outer periphery of the black eyeball is difficult to exert. The outermost part is jagged in appearance and is easy to stand out, and it is easy for third parties to feel unnatural and uncoordinated in appearance. sense.

In addition, even in the case of using the tapered spokes 28 having a tapered shape as illustrated in Reference Example 1 as shown in FIG. 4, if the configuration different from that of the present invention described above is adopted, adjacent tapered shapes are used. The spokes 28 and 28 are continuous with each other so that the outermost part overlaps, and the non-colored part 32 does not reach the outer peripheral end of the beauty pattern area 26, and the outer peripheral part of the beauty pattern area 26 does not exhibit color. Assimilation phenomenon. Therefore, the outer peripheral edge of the colored portion that is continuous throughout the whole week is conspicuous in appearance, and it will feel artificial and unnatural and uncoordinated like a robot to a third party.

Furthermore, in this embodiment, the non-colored portions 32 provided between the tapered spokes 28 and 28 adjacent to each other in the circumferential direction of the lens are provided with a width dimension that becomes larger from the outer peripheral side toward the inner peripheral side of the lens. On the contrary, for example, if a non-colored portion provided between adjacent tapered spokes 28 and 28 in the circumferential direction as shown in FIG. 5 is extended in a substantially constant width dimension and extended over the entire length in the radial direction, As a reference example 2, regarding the assimilation phenomenon of colors, a radial transition cannot be seen. Therefore, it is difficult to sufficiently express the appearance obtained by naturally assimilating the color of the tapered spokes 28 and the color of the eyes, and it is not possible to sufficiently achieve the appearance of the enlarged black eyeball that takes into account the outermost portion of the beauty pattern area 26. The resulting cosmetic effect and the natural appearance presentation effect in the inner peripheral portion of the cosmetic pattern area 26 by adaptation to the wearer's eyes.

Furthermore, in order to exert an effective assimilation phenomenon, it is necessary to appropriately set the separation distance of the adjacent tapered spokes 28, 28. In particular, if the separation distance becomes too large, there is also a case where, as shown in FIG. 1 (c) or FIG. 5, compared with the assimilation phenomenon, the contrast phenomenon is dominant, and the color of the tapered spokes 28 is conspicuous. It looks unnatural, or the color of the tapered spokes 28 and the color of the sclera (eye white) alternately appear uneven, so that the third person feels a sense of incongruity or aversion.

Therefore, the separation distance between the adjacent tapered spokes 28 and 28 in the circumferential direction is set within the range of 0.01 to 0.20 mm at the minimum outer peripheral end. Although it also depends on the environmental conditions such as lighting or interpersonal distances that are mainly considered, if, for example, a general lighting environment with high intensity other than photography is used, the normal interpersonal distance (15-45cm intimate distance or 45-120cm) Personal space, social distance of 120 to 360 cm, etc.), it is preferable to set the separation distance of the outer peripheral ends of the tapered spokes 28 and 28 within the range of 0.01 to 0.15 mm. When the intimate distance or personal space is more important, etc., it is also preferable to set the separation distance of the outer peripheral ends of the tapered spokes 28 and 28 to be within a range of 0.01 to 0.10 mm. In addition, when the value of the separation distance of the adjacent tapered spokes 28 and 28 in the circumferential direction is difficult to be measured by direct visual observation, it can be calculated by, for example, the following method. The universal projector V-12B manufactured by Co., Ltd. is obtained by magnifying and projecting to 20 times the size of the contact lens with the rear surface side of the contact lens standing still, and converting it to the actual size.

Further, in the beauty pattern area 26 formed by arranging a plurality of tapered spokes 28 in the circumferential direction, the width of the spokes of the tapered spokes 28 is increased and decreased, and the width of the spokes of the tapered spokes 28 is set between adjacent tapered spokes 28 and 28. The increase and decrease in the width of the non-colored portion 32 are complementary. Therefore, although the spoke width of the tapered spokes 28 also slightly affects the presentation, the extent of the assimilation phenomenon is that the color of the tapered spokes 28 is assimilated to the color of the eyes that can be seen through the non-colored portion 32, and When the color of the eye that can be seen through the non-colored portion 32 is assimilated into the color of the tapered spokes 28, the width dimension of the non-colored portion 32 between adjacent tapered spokes 28 and 28 becomes dominant Cause. This situation can also be understood as follows: In the specific example of the beauty pattern area illustrated in Figs. 6 (a) and (b), although the tapered spokes 28 having the same spoke width are used for both, the non-coloring The degree of assimilation is different when comparing (a) where the width dimension of the portion is narrowed with (b) where the non-colored portion is widened.

Of course, in terms of the balance between the performance of assimilation and aesthetics, the spoke width of the tapered spokes 28 also has a better range, and the width is set to the maximum outside spoke width dimension (W) is preferably set to 0.1 In the range of ~ 1.0mm, it is more preferable to set it in the range of 0.2 ~ 0.6mm. In addition, the length of the tapered spokes 28 in the radial direction of the lens is not particularly limited so that the inner peripheral side is located on the cornea 20 without covering the pupils of the wearer's eyes, and is located on the outer peripheral side from the cornea 20 of the wearer. The length extending to the sclera 22 is arbitrarily set. Within this range, generally, the length of the tapered spokes 28 is set in a range of 0.5 to 4.5 mm, and more preferably set in a range of 1.0 to 3.5 mm. Thereby, the inner peripheral end of the cosmetic pattern area 26 is located on the cornea 20 and the outer peripheral end is located on the sclera 22. Further, the tapered spokes 28 may be formed by a bottom edge (W) located on the outer peripheral end and two hypotenuses extending from the two ends of the bottom edge toward the inner peripheral side, respectively, and each hypotenuse is more than the bottom edge. Long triangle shape.

Furthermore, the specific shapes of the plurality of tapered spokes 28 constituting the beauty pattern area 26 are also within a range that does not hinder the performance of the assimilation phenomenon, and are not limited to having the same size and shape as shown in the first embodiment. The shape of the isosceles triangle.

For example, as shown in FIG. 7, the beauty pattern area 26 may be constituted by a plurality of tapered spokes having different shapes or sizes like five tapered spokes 28 a, 28 b, 28 c, 28 d, and 28 e. In addition, as illustrated in FIG. 8, tapered spokes 28 having a substantially trapezoidal shape as a whole by setting the vertex portion of the inner peripheral end in a straight line extending in the circumferential direction, or as illustrated in FIG. 9 may be used. The apex portion of the inner peripheral end is rounded into an arc-shaped conical spoke 28 or the like.

In addition, in the beauty pattern area 26 shown in FIG. 7, a total of five types of tapered spokes, 28b, 28c, 28d, and 28e, are wound in sequence from the longest tapered spoke 28a to the right in a circumferential cycle. Configuration. Therefore, if any one of the conical spokes 28a, 28b, 28c, 28d, and 28e is focused on, one type of conical spokes has the same shape and size, and is equally spaced in the circumferential direction. arrangement. Specifically, when focusing on the shortest tapered spokes 28d, a plurality of the tapered spokes 28d having the same shape and size are arranged at equal intervals in the circumferential direction and between the circumferential directions of the tapered spokes 28d and 28d. Four cone-shaped spokes 28e, 28a, 28b, 28c of different sizes are arranged respectively. Furthermore, in FIG. 7, the two tapered spokes 28 b and 28 e disposed on both sides in the circumferential direction of the longest tapered spoke 28 a have approximately the same shape and size. However, by using these two tapered spokes 28 b, And 28e are identified as different types, and it can be understood that any of the tapered spokes 28a, 28b, 28c, 28d, and 28e constituting the beauty pattern area 26 of the present aspect are arranged at equal intervals in the circumferential direction with the same shape and size, respectively. Of the composition. In other words, in the beauty pattern area 26 of FIG. 7, a plurality of tapered spokes 28a, 28b, 28c, 28d, and 28e arranged in a circumferential direction are arranged as a pattern, and the pattern is periodically arranged in the circumferential direction. .

In addition, the tapered spokes 28 only need to have a tapered shape from the outer peripheral side to the inner peripheral side, and it is not necessary that all three sides be straight isosceles triangles as shown in the first embodiment. For example, the two sides of the tapered spokes 28 extending from the outer peripheral end toward the inner periphery may also change the inclination angle in the length direction. Specifically, as shown in FIG. 10, the entirety may also be bent toward the inner periphery. The tapered spokes 28 are formed in a shape that extends toward the front end of the inner peripheral side and does not face the center of the beauty pattern area 26. In addition, by setting the two sides (hypotenuses) of the tapered spokes 28 and 28 opposed to each other in the circumferential direction to be straight lines, the width dimension of the non-colored portion is continuously changed at a constant ratio in the radial direction. Can make the transition of the assimilation phenomenon in the radial direction smoother, but it is not limited to this, and curves or polylines can also be used.

In addition, the non-colored portion 32 located between adjacent tapered spokes 28 and 28 has a width dimension in the circumferential direction set to the maximum at the inner peripheral end of the adjacent tapered spokes 28 and 28 and to the minimum at the outer peripheral end. . In addition, in the intermediate portions located between the inner peripheral end and the outer peripheral end, the width dimension of the inner peripheral side does not decrease compared to the outer peripheral side, but increases from the outer peripheral side toward the inner peripheral side. Furthermore, it is not necessary to continuously change the width dimension of the non-colored portion 32 throughout the entire middle portion. For example, there may be a region where the width dimension does not change locally in the radial direction of the intermediate portion, and the ratio of the width dimension change in the radial direction of the intermediate portion may be continuously or stepwise different.

That is, as schematically shown in FIG. 11 (a), if the separation distance (equal to the width dimension of the non-colored portion 32) in the circumferential direction of the tapered spokes 28, 28 adjacent to each other in the circumferential direction, the inner peripheral end The separation distance between A-A 'is D, the separation distance between B-B' at the outer end is Db, and the separation distance between C-C 'at any point in the middle is Dc. , The following formula holds.

0 <Db <Dc <Da

When the radial lengths of the tapered spokes 28 and 28 adjacent to each other in the circumferential direction are different from each other, as shown in FIG. 11 (b), the inner peripheral ends of the shorter tapered spokes 28 are shortened. The separation distance between D-A 'is set to Da in the above formula.

Furthermore, in one aspect of the present invention, the non-colored portion 32 may be configured, for example, such that the value of the length dimension in the radial direction of the lens is set to 0.5 to 4.5 mm and the maximum inner circumference is set. The value Da-Db of the difference between the width dimension Da of the end and the width dimension Db of the outer peripheral edge set to the minimum is set to 0.02 to 3.0 mm. Moreover, in one aspect of the present invention, a configuration may be adopted in which the separation distance Da and the separation distance Db at the inner peripheral end of the tapered spokes 28 and 28 adjacent to each other in the circumferential direction of the lens, The width dimension of the inner peripheral end of the tapered spoke 28 is set to a value smaller than Da, and the width dimension (W) of the outer peripheral end is set to a value larger than Db.

Furthermore, the edge (W) on the outer peripheral side of the tapered spokes 28 (corresponding to the bottom edge of the isosceles triangle) need not be a straight line in the shape of a chord in the peripheral circle outside the beauty pattern area 26. For example, as shown in FIG. 12 (a), it may be a curved line such as an arc. Further, as shown in FIG. 12 (b), the intersections of the two ends of the outer peripheral side of the tapered spoke 28 with the other two sides (hypotenuses) may be smoothly connected in an arc shape, or As shown in FIG. 12 (c), the shapes obtained by removing the corners in a C-chamfer shape are connected. By adopting the corner shapes such as (b) and (c), the separation distance between the tapered spokes 28, 28 is slightly widened at the outermost peripheral edge, and the assimilation phenomenon to the sclera can be used to make the beauty pattern The outer peripheral edge of the area 26 is blurred, which can also make the appearance of the appearance more natural.

On the other hand, in the case where Dc <Db is set contrary to the condition of the above formula, as illustrated in FIGS. 13 (a) to (c), the beauty pattern area 26 is located at the middle portion in the radial direction and is thicker. The colored area is easy to recognize. Compared with the radial middle portion, the color assimilation phenomenon on the inner peripheral end and the outer peripheral end is difficult to fully exert, and as a result, a sense of disharmony tends to occur in appearance.

In the case where Da <(Db, Dc) is set contrary to the condition of the above formula, as illustrated in FIGS. 14 (a) and 14 (b), the beauty pattern area 26 is located on the inner peripheral portion in the radial direction. And the thicker colored areas in the outer and peripheral parts are easy to recognize, and the assimilation phenomenon of the colors in the radial middle part is difficult to fully exert. As a result, a sense of incongruity in appearance is easily produced.

Furthermore, in the case where Db ≦ 0 is set contrary to the condition of the above formula, as shown in FIG. 15, a clear colored edge is visually recognized at the peripheral edge outside the beauty pattern area 26 and the assimilation phenomenon is not exerted. , While showing the conspicuous outer edge due to the contrast phenomenon, the result is a robot-like artificial appearance.

The results of tests performed by the present inventors to confirm the effects of the present invention as described above are described below. In this test, the beauty pattern area 26 composed of each colored pattern for Examples 1 to 3 of the structure according to the present invention shown in FIG. 16 and Comparative Examples 1 to 6 shown in FIGS. 17 to 18, Visual evaluation was performed (based on JIS Z 9080: 2004). Furthermore, since the main purpose of this test is to verify the visibility of the details of the colored patterns regardless of their preferences, in order to make the colored patterns easy to observe and to facilitate the comparison of the patterns, the following method is adopted. The pattern is printed on the actual size of the overhead projector (OHP) sheet, and the OHP sheet is superimposed on the paper with the actual size photo printed as an alternative to wearing the eye.

In addition, the test was carried out in a lighting environment suitable for the environment in which the computer monitor operates, and it was noted that the lighting of the lighting device in the test environment would not be reflected in the colored pattern of the observation object. The distance between the tester's coloring pattern and the observation target was set to approximately 50 cm. The test was conducted by 7 persons who have sufficient knowledge and experience in cosmetic contact lenses.

[Experiment 1]

Test object: Examples 1 to 3 and Comparative Examples 1 to 3

Test method: As for the colored pattern of each test object, evaluate whether the irregularity of the unevenness in the outermost part can be seen on the appearance. The evaluation results indicate that there are answers to the four options of "looking uneven", "looking slightly uneven", "not looking uneven", and "not looking uneven".

Test results: shown in the following [Table 1].

[Experiment 2]

Test object: Examples 1 to 3 and Comparative Examples 1 to 2

Test method: For the coloring patterns of Examples 1 to 3 and Comparative Examples 1 to 2, the outermost part of the coloring pattern of Comparative Example 3 is darker and can be clearly seen. The evaluation results indicate that there is a choice of two answers.

The evaluation results indicate that there are answers using the four options of "looking loose", "looking slightly loose", "looking slightly sticky", and "looking sticky".

Test results: shown in the following [Table 2].

[Summary of test results]

From the results of Test 1, it was confirmed that when Db (distance between BB's) exceeds 0.2 mm, the outermost periphery of the colored pattern looks uneven.

Based on the results of Test 1 and Test 2, it was confirmed that even in Example 1 in which all the test implementers responded as "not looking uneven", when compared with Comparative Example 3 in which Db was 0 mm, all test implementers answered as "Comparative Example 3 has darker colors and can be clearly seen", and there is a difference in sharpness due to the gap in Db.

In Test 3, those having the same tapered spokes in Examples 1 to 3 and Comparative Examples 1 to 2 and having changed Db can be confirmed by comparison. If the Db exceeds 0.2 mm, the shape of the spokes can be clear. It can be recognized, and it can be confirmed that the assimilation phenomenon is hardly manifested.

Any of Comparative Examples 4 to 6 is a colored pattern in which the separation distance between the spokes that are adjacent colored portions does not satisfy the above-mentioned conditional expression "0 <Db <Dc <Da", because Comparative Examples 4 and 5 are compared with Examples 1 and 2 have the same Db, so analogy was evaluated as "seeming unevenness" in Experiment 1. Regarding Comparative Example 6, it can be confirmed from the results of Experiment 3 that the shape of the spokes is clearly visible, and it is confirmed that no assimilation has occurred.

The embodiments and examples of the present invention have been described in detail above, but the present invention is not limited to interpretation by these specific records.

For example, the specific color of the tapered spokes 28 is not limited by lightness, hue, saturation, density, and the like. That is, not only the natural corneal color or scleral color of the human eye varies according to race or individual differences, but also the color desired for cosmetic contact lenses varies according to use or individual differences, etc., so according to such various conditions or requirements The color of the tapered spokes 28 can be set appropriately. Furthermore, since the assimilation phenomenon of colors tends to occur more easily when colors are similar to each other, for example, it is also possible to consider the race and prepare cone-shaped spokes of multiple colors and provide them to the market.

In addition, the optical part 14 or the non-colored part 32, the peripheral transparent area 30, and the like in the beauty contact lens of the present invention may be colorless and transparent or colored and transparent. For example, the optical part 14 may set a transparent color in consideration of the transmittance of visible light and the like. The non-colored portion 32 can be set to a transparent color in consideration of the color of the iris or the cosmetic effect on the appearance. Of course, in the beauty pattern area 26, the tapered spokes 28 are set to be different from the non-colored portion 32 in a manner that can be recognized as a colored area and exhibit an assimilation effect, with different light transmittance or color density.

Furthermore, the method of placing the tapered spokes 28 on the contact lens in a colored state is not limited in the present invention. For illustrative purposes, as described in Japanese Patent Application Laid-Open No. 3-54519, etc., coloring is performed when the contact lens is molded and molded into a contact lens, or by hand-painting or photo printing, For screen printing and the like, and taking into consideration that the adhered surface is spherical, mass production, coloring accuracy, color reproducibility, etc., pad printing or inkjet printing can also be used.

In addition, the tapered spokes 28 may be changed in color from the inner peripheral side toward the outer peripheral side, for example, but may have a substantially fixed color (lightness, hue, saturation, and density) as a whole. In addition, different colors may be set in the plurality of tapered spokes. However, by using the tapered spokes of the same color, the appearance of a uniform color in the beauty pattern area can be presented as a whole. Furthermore, when the tapered spokes are colored in a dot shape using a light-transmitting or opaque coloring material, etc., although areas where no dots are attached may remain, if the use between adjacent tapered spokes is considered, Assimilation of the color caused by the non-colored portion, it is preferable that the tapered spokes are colored areas where the entire surface is set to a substantially uniform and fully coated state that is transparent or opaque.

Further, the tapered spokes constituting the patterned area for beauty are generally arranged in a circle with the optical part or the geometric center of the lens as a center, but it is not necessarily limited when the cornea deviates from the geometric center in a worn state such as an eccentric lens. To explain the center position.

In addition, although the cosmetic contact lens of the present invention has a colored portion (colored belt portion) composed of tapered spokes, other colors may be used together as long as it does not hinder the effect produced by the assimilation of the color. structure. For example, as exemplified in FIG. 19, a mark 36 such as a guide mark indicating the wearing direction which is visible on a contact lens for astigmatism or the like may be used together with the tapered spokes 28.

In addition, in the above-mentioned embodiment, a few specific examples of the tapered spokes that can be adopted in the present invention are listed, but these are merely examples and are not a basis for limiting interpretation. Also, in FIG. 7, a combination of tapered spokes having different radial lengths is exemplified to form a beauty pattern area. However, in the present invention, it is not limited to the radial length, and the inner peripheral end or A variety of tapered spokes, such as the outer peripheral end and the radial middle portion, constitute a cosmetic pattern area. More specifically, for example, tapered spokes having different widths in the circumferential direction, non-colored portions having different widths or shapes in the circumferential direction, inner or outer peripheral ends, and radial intermediate portions may have different shapes. The tapered spokes, the tapered spokes having different colors or transparency, and the like are appropriately combined to constitute a cosmetic area.

Others are not listed one by one, but the present invention can be implemented in the form of various changes, corrections, improvements, etc. based on the knowledge of a person having ordinary knowledge in the technical field to which the present invention belongs, and, of course, such an implementation state As long as it does not deviate from the purpose of the present invention, any of them is included in the scope of the present invention.
